Have An iPhone 3G? Here Is What You Don't Get With iOS4

Yesterday was iPhone upgrade day as Apple released the iOS 4 upgrade via iTunes. The upgrade is for the iPhone 3G and the iPhone 3GS, but we knew from the Apple keynote that some of the features in iOS 4 would not be available for the iPhone 3G. So, if you have an iPhone 3G, you might be wondering what you are missing out on. Unfortunately, 3G owners miss out on the main feature of iOS 4, multitasking.
